<br />San Juan River Unit, New Mexico <br /> <br />w <br />o <br />t.u <br />w <br /> <br />ReClamation completed its Planning Report/Environmental AssessmentlFinding of No Significant <br />Impact, dated December 1994. The report evaluates alternatives to control salinity on the <br />Hammond Project. The report recommends canal lining as a cost effective way to control seepage <br />and salinity. The Hammond Project was awarded about $500,000 in flscal year 1996 under the <br />authorities of P.L. 104-20 to begin rehabilitation of their facilities. <br /> <br />DoloreslMcElrno Creek Unit, Colorado <br /> <br />Reach 1 and 2 of the Towaoc Canal have been completed. The Rocky Ford. Laterals, which deliver <br />water from the Towaoc Canal, were completed in 1994. Contracts for lining three sections of the <br />Lone Pine Lateral and the one section of the Upper Bermana Lateral have been completed. The <br />major features of the project are now complete and have been transferred to operational status. <br />Repayment will begin next fiscal year. <br /> <br />Grand Valley Unit, Colorado <br /> <br />Construction is underway on parts of the east end of the Government Highline Canal system as well <br />as the Price and Stubb Ditch systems. Reach 1 b of the Government Highline Canal has been <br />completed. Work on the Mesa County Irrigation District and Palisades Irrigation District <br />construction cooperative agreements for the Price and Stubb Ditch system improvements is <br />underway. The Price and Stubb Ditches have been completed. Work on t!1e lateral portion of these <br />systems is expected to be completed in 1998. <br /> <br />Lower Gunnison Basin Unit, Colorado <br /> <br />The winter water replacement system has been completed and started repayment in FY -96. The <br />East Side Lateral portion of the project will compete for funding in Reclamation'.s Basinwide <br />Program under the authorities of P.L. 104-20. <br /> <br />Paradox Valley Unit, Colorado <br /> <br />With the 2-year injection test showing the injection zone capable of receiving brine for over 10 <br />years, ReClamation purchased and installed continuous service pumps to replace the variable rate <br />pumps used in the 2-year test. The pumps were installed this past summer. Maintenance <br />procedures for the new pumps are being developed in cooperation with the manufacturer. <br /> <br />ReClamation plans to continue to blend fresh water into the brine to prevent sulfate precipitation in <br />the injection well. This limits the injection to 128,000 tons per year. Nano-filtration of sulfates is <br />being investigated and may allow for higher concentrations of brine to be injected. This would <br />potentially allow up to 180,000 tons per year to be injected. Laboratory tests by Dow Chemical <br />found the membrane effective at removing sulfates from the brine. In 1996, Reclamation executed <br />a cooperative agreement with Dow to test the process onsite. The test filtration facility was <br />installed in the summer of 1996. The study will run through November 1997. The results will be <br />used to determine the cost effectiveness of adding nano-filtration to the process stream. <br /> <br />20 <br /> <br />
